Global Analysis and Assessment of Sanitation and Drinking-water (Glaas): the Challenge of Extending and Sustaining Services. Un-water Global Annual Assessment of Sanitation & Drinking-water World Health Organization

The UN-Water Global Analysis and Assessment of Sanitation and Drinking-water (GLAAS) monitors the inputs required to extend and sustain water, sanitation and hygiene (WASH) systems and services. The 2012 report is the second in a series of biennial reports and presents information received from 74 developing countries, and from 24 external support agencies that provide development assistance for sanitation and drinking-water.

The report summarizes the status and trends of the "enabling environment" for WASH including: government policy and institutional frameworks; the volume, sources and targeting of financing; the human resource base; factors affecting equity in service delivery; trends and priorities in external assistance; and performance. GLAAS also analyses the factors associated with progress, or lack thereof, in order to identify drivers and bottlenecks, knowledge gaps, strengths, weaknesses, challenges, priorities and successes in delivering WASH services.
